135 oil cooler

[Randall41]

Anyone installed an aftermarket oil cooler? If so which type, add on or "piggyback"? On a recent run down to Roswell, NM going on LONG secondary roads where you can see to Mexico I easily hit 160mph, but oil temp was climbing. That afternoon returning to ABQ I took it easier and ran along at 140 but soon got a check engine light followed by limp mode. Pulled into a rest stop and cooled down a bit and everything reset. I am unable to retrieve the code, at least until I figure out where I put my BavTechnic tool. It's hell getting old.

I drove my 135i conv back from Dallas to San Fran thru AZ, NM, NV, and CA deserts, doing between 70 and 100 mph. My oil temp usually stays around 235 F on the highway, maybe it peaked at 250 F if I really stood on the car during that one trip.

What was your high temp? (It's a gauge right there on your dash, the dripping oil can, bottom of your tach... =;-])

250

250+, and thanks for the info, i wondered where that gauge was....

I run the Dinan one, it works quite well. Oil temps are 10-15 degrees lower than before in almost all settings.

i have the Dinan oil cooler, along with Dinan Stage 2 software.

I've never had the opportunity to cruise above 130 mph , but my normal temp is around 235 - a little hard driving takes it to around 245. I've never seen above 250.

Hope this helps.

Have Fun,
Rick

stock i assume? there would be no reason for an oil cooler with just regular aggressive driving with a stock car.

[Randall41]

Thanks much for the replies. Vishnu tune with whatever it came loaded with. As soon as I find a cable I'll be trying other downloads.

I cruise around in Hawaii and its around 75-90 on any given day. My oil temp gauge is constantly just a bit below 250. Would like to go the Dinan route, but will wait until I return home to NY. If I remember right the dealership in Huntington still is an authorized Dinan dealer. Dinan oil cooler plus BMW Performance Power Kit (whenever the hell that gets released hopefully will keep the temps down.

As the old acronym goes, RTFM: 210-300F (100-150C) is normal oil temp as per page 63.

The HKS OilCooler is the BOMB! A little pricey but its definitely the Shizzznit

*edit*

Retail is somewhere around $1760.00

Where did you purchase this from?
Online?
Thanks

ZOMG twin oil coolers, i wonder how long it would take to get the car warmed up with those...25-30min??

The oil cooler simply helps cool the oil, it does not determine when you've reached operating temp.
The engine is warmed up once the coolant and thermostat reach operating temp, somewhere around 160-170F.

Your oil isn't protecting you better when it's hotter. That's why there is an oil COOLER, to keep the oil temps COOLER. Your engines operating temp is controlled by your thermostat, water/coolant, water pump, fan, and the radiator, and air flow.

The more plumbing the longer oil (and coolant) takes to heat up. You want your coolant and oil at operating ranges before you can really call your engine 'hot.'

Cold oil does not have optimal viscosity or the binding properties to prevent particulates that are in everyone's oil from sticking to engine parts.

I get what you are saying about the thermostat, ratio, pump, fan, and radiator - but all of that just regulates your coolant temp which is the operative part of the equation.

The oil cooler has it's own thermostat which keeps oil from flowing through the cooler until the oil warms up and the thermostat opens. It has little if any effect on oil warm up time.

The reason I keep pointing this out is because people are really placing much too much emphasis on this oil temp gauge, as if they can't drive the engine hard until they see 240F. That's just not true.
The oil isn't protecting better at 240F than it is at 170F.
Modern synthetics work great even at temps under 100F, and are still providing all the needed lubrication and particle suspension. And, the oil filter still filters even if the oil temp has reached 240F or so.

I would still prefer a standard engine/coolant temp gauge and an oil pressure gauge, to the oil temp gauge. Now that it's there too much emphasis is being placed on it. The gauge doesn't show a red zone and then a green zone and then another red zone as the temps rise.
The reason is because it's not the important. Waiting 20 mintues in summer ambient temps, for your oil to heat up before getting on it, makes no sense to me. You're well warmed up before then with these ambient temps.

The best way is to let the waterthermostat working and remove the oil thermostat.
We have done a lot of testing and find that it´s realy need a modification to get the oil temperature under control!

Our solution after testing on Nürburgring and other tracks:

Yes, but to have the OEM thermostat You never going to have a sollution for the high temperatures!
This is a cheep solution that keep the engine cold, we did try it during 1 week in Nürburg.
To be onest yes You always like to get the oil to get thrue 100-110 celsius, if You drive litle active it´s easy to get that themperature!

Our solution is not for people who only use the car to the ice cream shop, we just made it to all BMW drivers that drive the cars hard and think $1000-$2300 for a oil cooler solution is to mutch money!
We allso looking to build a oil cooler kit but until that we needed a way to keep the engine cold!

And to be onest this did realy work and it did just take 15-20 min to change it to our solution, but i shuld not recomend anyone to use it on the winters!

Best regards

Engine operating temp is also controlled by the oil and oil cooler. Oil only flows through cooler after oil reaches a certain temperature.

As stated by Bluemoon.

Does the kit have a temp valve? Can't read Jap.

Jim, Where is the oil thermostat in the oil cooling system? Can't find in realoem.
